[SOLVED] chevy 1500 backfire

This is a discussion on [SOLVED] chevy 1500 backfire within the Automotive Support forums, part of the Tech Support Forum category. when I accelerate quickly or matt it the truck will back fire through the tbi and will either stall completely

when I accelerate quickly or matt it the truck will back fire through the tbi and will either stall completely or spit and sputter then get up to speed. Any ideas? I thought maybe the fuel pump or the timing is off

Its a 94 5.7l 350 with 135k miles. I'm going to check the timing and fuel pressure regulator tonight but I don't think its too serious considering it runs fine as long as you aren't stomping on the pedal

yeah hope for the best and aspect the worse
old rule of thumb
If it back fires thru the carb its timing or valve train
If it back fires thru the exhaust its the carb or valve train
granted that applies if you got the spark plug wires right LOL

a timing chain will not act up as much when your babying the truck but goose it and the chain wipes

not hard at all just takes 2 ppl
remove the dist cap with a socket on a breaker bar connected to the crank shaft front bolt turn it backwards a little when the second guy sees the rotor turn you can stop mark the balancer with a reference point on the timing mark... now turn it back the other way slowly and when the other guy sees the rotor start to move stop .. then look and see how far the reference mark has moved in degrees or in inches 1/4 ect

1/2" play in the chain it is starting to get bad an inches and jumping a tooth is about to happen
